The warning that “lifesaving blood may not be available for some patients when it is needed” comes amid a surge in Covid-19 cases. Due to problems tied to the ongoing Covid-19 pandemic, the American Red Cross on Tuesday declared its first-ever national blood shortage crisis, warning that already, “doctors have been forced to make difficult decisions […]
One of the physiopathological characteristics of COVID-19 that has most baffled the scientific and medical community is what is known as “silent hypoxemia” or “happy hypoxia”. Patients suffering this phenomenon, the causes of which are still unknown, have severe pneumonia with markedly decreased arterial blood oxygen levels (known as hypoxemia). However, they do not report […]

COLUMBUS, Ohio – Imagine a world in which mosquitoes choose blossoms over blood. Nice, right? There already exists a mosquito species called Wyeomyia smithii in which most of the bugs refuse blood meals in favor of sweet floral nectar. And new research is helping to explain the evolutionary genetics of the switch from blood sucker to flower […]
Porphyrias, a group of eight known blood disorders, affect the body’s molecular machinery for making heme, which is a component of the oxygen-transporting protein, hemoglobin. When heme binds with iron, it gives blood its hallmark red color. The different genetic variations that affect heme production give rise to different clinical presentations of porphyria — including […]
WASHINGTON, DC—It can be a matter of life or death — waiting for test results from a laboratory about a serious health problem. But two small medical devices now in development can quickly diagnose some conditions, including the potential for a heart attack. The first, a “tricorder,” was given the same name as the […]
